I have an issue where certain windows on my Windows 7 machine are not large enough to show all the buttons. For example, in Excel, the Save As window shows only the very top of the SAVE and CANCEL buttons, and while the window it self can be enlarged or shrunk at the corners, it does not reveal the buttons that are hidden. there is also no scroll bar inside the window. So my only choice is to use the TAB key to tab onto the hidden buttons. This seems like some kind of glitch.
